Reducing Rate EMI
Flat Rate EMI
Flat interest rate is calculated on the original principal throughout the loan tenure, while reducing rate is calculated on outstanding balance (decreasing monthly). A ₹10L loan at 10% flat rate charges ₹1L interest for life, totaling ₹11L. The same loan at 10% reducing rate (5-year tenure) costs only ₹27,500 interest, totaling ₹10.27L. Reducing rate is mathematically superior, yet some lenders (especially gold loan providers, consumer goods financiers) promote flat rates as marketing feature (advertising lower effective rate: 5% flat ≈ 9% reducing). Understanding the mathematics prevents poor borrowing decisions—flat rates appear deceptively cheap initially but become painfully expensive over time. Indian borrowers are increasingly aware; most modern loans use reducing rate structure.
